WOW!! I frosted these with a thick chocolate buttercream, and took them to work for a breast cancer awareness fundraiser... everyone just LOVED them!! One thing, they do not get that typical rounded cupcake look, they stay flat, and some fall quite a bit during cooling... but they're so moist and delicious they're worth it!! My fiance said they remind him of the peanut butter cookies with the reese's centers that you see at Christmas time. What a yummy cupcake!! Thanks for sharing! I'll be posting a pic later... if there's any left when I get home!
